Experimental Data for Elastomers

[Jorgen]

If you are looking for experimental data for elastomers, take a look at the Materials and Models pages (http://polymerfem.com/index.php?pageid=mat_mod).

The Materials and Models section contains both experimental data and predictions from different material models.

Thanks a lot!

Natural Rubber(55pph CB) and Silicone Rubber seem are unuseful....the test date don't download.........

[Jorgen]

Thanks for letting me know. I fixed the problem, you can now dowload these files from:

NR (http://polymerfem.com/polymer_files/Materials_Models/Materials/NR55/NR_55pphCB.zip)

Silicone Rubber (http://polymerfem.com/polymer_files/siliconeRubber.zip)

Thanks! It's good !

Hi,

I am new to this forum and relatively new to FEM. I wanted to model elastomer deformations in microelectromechanical systems, but have heard from people that ANSYS is not good at elastomer FEM (the results cannot be trusted).

I was hoping that I could get a "layman's" introduction to elastomer modeling using ANSYS and to verify the above claim.

I am using PDMS silicone elastomers.

Thank you.

I disagree with the statement. The hyperelastic models in Ansys work just fine (the same way as in any other FE software).

For more accurate results, if that is needed, you can use a user-material subroutine.

Sir,
i am using ansys 12 for FEA.I am trying to model PDMS(silicon putty),the exact properties of which are not known to me.Can you pls let me know the material properties which would help me design the element?Should i use MAXWELL or HYPERELASTIC ?

[Jorgen]

The most appropriate approach will depend on what you are trying to accomplish with your analysis. Do you need a viscoelastic model?

sir,
thank you very much for replying to my question....I want to make a maxwell viscoelastic model...it would be great if you can provide me the data set for PDMS(Polydimethylsiloxane).thank you again for sparing your valuable time....

[Jorgen]

I am afraid that I don't have any experimental data for PDMS that I can share. Do you have data from the manufacturer or can you perform a few tests?

Sir,
Thank you again for replying to my queries, i am afraid it is not possible for me to perform any experiments.
I am performing experiments and numerical models to simulate the inner layers of the earth.For the experiments i am using PDMS.Since the data is not available for PDMS ,please let me know whether you have the data for any Maxwell Viscoelastic material

[Jorgen]

I have experimental data that I can share for a few different elastomeric materials. You can explore and download these data sets from the following page (http://polymerfem.com/index.php?pageid=mat_mod).

sir,

please let me know which of the materials(listed in the page)acts as a Maxwell viscoelastic material.thank you very much for the quick replies

[Jorgen]

Can you explain how you define a "Maxwell viscoelastic material"?

Dr. Bergstrom,

I believe that thie link to Materials and Model Pages is broken.

For my thesis I need an input in the Ansys library. I need this input for the following materials:
NBR, FKM, EPDM, CR and PTFE. I have seached on the website, but the link with the library is broken.
You will help me very much when this data is available. Can you please watch for me of the data is available
and can you restore the link? Thanks in advance for you're help!

Kind regards,
Martijn Engwerda

Hello,

I'm in need for experimental data of rubber tested with different starin rates. I already found the data in the experimental data section of this site.
I am furthermore looking for data of tension and/or shear experiments in time/stress/strain tables. The type of rubber is not that important, though. Nice would be large deforations so that the non-liniarities show.
Best regards,
Lutz
